Description
The TL431MKN3 series are three-terminal adjustable regulators with guaranteed thermal stability over applicable
temperature range. The output voltage may be set to any value between VREF (approximately 2.495 volts) and 36 volts
with two external resistors. These devices have a typical dynamic output impedance of 0.1Ω. Active output circuitry
provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many
applications.
Features
• Programmable output voltage
• Temperature coefficient is 50ppm/°C typical
• Improved temperature compensation
• Sink current capability of 0.1mA to 100mA
• Low output noise voltage
• Fast turn on response
• Heat Resistance, Soldering iron : 300°C, 5 seconds
• Low dynamic output impedance 0.1Ω (typ.)
• Electrostatic discharge voltage 2.5kV.
• Pb-free lead plating and halogen-free package
